Turning the motor holding brake on and off
Compax3 controls the holding brake of the motor and the power output stage. The
time behavior can be set.
With an axis that is subject to momentum when it is halted (e. g. for a z-axis) the
drive can be switched on and off such that no movement of the load takes place.
The drive thereby remains energized during the holding brake response time. This
is adjustable.
Application:
Error or
The power output stage current is de-energized by:
I0=X12/6="0"
Thereafter the motor is braked to zero rotation speed on the set ramp.
When zero speed is reached, the motor is de-energized with the delay "brake
closing delay time".
